Results of Operative Intervention for Finger Stiffness After Fractures of the Hand.

Posttraumatic finger stiffness can occur as a result of hand fractures. The purpose was to assess and quantify the improvement in range of motion (ROM) after surgical management of the stiff finger in patients who developed loss of motion following treatment for a metacarpal or phalangeal fracture. In addition, an aim was to identify possible risk factors for suboptimal improvement in ROM postoperatively. A retrospective review was performed on 18 patients who underwent surgery to improve finger stiffness following metacarpal or phalangeal fracture. Demographic data including age, initial diagnosis and treatment, health history, and worker's compensation status were collected. We determined the number of specific procedures performed at the time of surgery, the number of days between surgical release and initiation of therapy, and the total active motion (TAM) prior to surgical release and at the patient's last follow-up. Mean TAM improved from 150° preoperatively (range 60°-241°) to 191° postoperatively (range 61°-271°). Most patients required multiple anatomic structures released concomitantly, with an average of 3.1. Patients who started physical therapy within 7 days of the release improved by 59°, whereas those who started physical therapy after 7 days (average 11.5 days) lost 19° of motion. Patients who had filed a worker's compensation claim improved an average of 9°, whereas nonworker's compensation patients improved an average of 58°. Degree of TAM improvement had a weak correlation with patient age or preoperative TAM. Surgical release for stiff fingers following hand fractures can offer modest improvements in ROM in some patients. Although the overall increase in motion as a result of these operations is generally limited, functional improvement can be obtained. Delay in initiating physical therapy is a risk factor for persistent or worsened stiffness. Patients involved in worker's compensation claims demonstrated significantly lower TAM improvement after surgical intervention.
